I got them both washed, __16__ by cries of delight, crazy running around, laughing and throwing things. __17__ calmed down, they lay in their beds as I gave each the five minutes' back rubs as usual.

A recently __20__ man with full custody (监护权) of his children, I was determined to give them as __21__ and stable a home life as possible. I __22__ a happy face for them. Everything was just as it had always been with the exception __23__ their mother was now missing. There, another night successfully __24__. I rose slowly, tiptoed out of their room and went down­stairs. Sitting at the __25__ room table, I realized that this was the first time since I came home from work that I'd been able to __26__ sit down. Then it all crowded in on me：the fatigue(疲惫), the __27__ of the responsibility, the worry about bills I wasn't sure I pay that month. And __28__. I felt as though I was at the bottom of a great sea of loneliness. I sat there, silently sobbing. Just then, a pair of little arms went around my middle and a little face peered up at me.

I received a letter from the head of the Personnel Department that started, “Dear John, I am quite pleased that you have decided to join us.”That “quite”saddened me.I thought he was saying “we're kind of pleased you decided to join us although I wish we had hired someone else.”Then I discovered that in American English “quite”sometimes means “very”， while in British English it means “fairly”．So the first lesson about working in other countries is to learn the language and by that I don't just mean the words people speak. It is body language, dress, manners, ideas and so on. The way people do things highlights many of the differences we see between cultures(文化)．Some of these differences may be only on the surface—dress, food and hours of work—while others may be deeper and take longer to deal with.Mostly, it is just a question of getting used to the differences and accepting them, like the climate(气候), while getting on with business.Some of the differences may be an improvement.People are more polite；the service is better；you ask for something to be done and it happens without having to ask again.However, other differences can be troubling, like punctuality(准时)．If you invite people to a party at 7 o'clock your guests will consider it polite to turn up exactly on time in Germany, five minutes early in the American Midwest, an hour early in Japan, 15 minutes afterwards in the UK, up to an hour afterwards in Italy and some time in the evening in Greece.I prefer not to use the word “late” because there is nothing wrong with the times people arrive. It is simply the accepted thing to do in their own country.36．The author was unhappy as mentioned in Paragraph 1 because he thought________.A．the American bank didn't think much of himB．the American bank might hire another personC．it's difficult to get used to American cultureD．it's easy to misunderstand Americans37．The word“highlights”in Paragraph 2 probably means________.A．encourages B．helps to narrowC．increases D．draws attention to38．According to the author, what should we do with most cultural differences?A．Ask the native people for help.B．Understand and accept them.C．Do things in our own way.D．Do in­depth research.39．When invited to a party the people who are usually punctual are________.A．Italians B．Germans C．Greeks D．the British
